Google has backflipped on its revised bookmark manager for Chrome, reinstating the classic version instead.
When Google introduced its revised Bookmark Manager for Chrome, the general reaction wasn't very positive. You could hack your way around it, but that's a less than elegant solution in real terms.
It seems that Google agrees, with Google's Sarah Dee writing on Google's product forums that the old Bookmark Manager will be brought back. If you're a fan of the newer style, you're not completely out of luck, however, as it's still available as a Chrome Extension.
